EPSON AMERICA, INC. EPSON Product Support Bulletin Subject: DFX-5000, DFX-8000 and Avatar EP-Connect Date: 10/9/92 Page(s): 1 of 1 PSB No: P-0091 Originator: REW Avatar Corporation distributes the EP-Connect coax interface for the Epson DFXseries and other Epson dot-matrix printers that use A-type interfaces. This EPConnect coax interface allows a connection to an IBM 3174/3274/3276 control unit or 4300 series Display Printer Adaptor using standard type A coaxial cable. When using EP-Connect and the DFX-series printers, there have been some intermittent operational problems reported. It has been determined that this is caused by the type of connector used on the EP-Connect interface that plugs into the printer's main controller board. There are two types of connectors that have been used on the EP-Connect coax interface. One type is a "FUJITSU" connector. The other is a "HONDA" connector. The "FUJITSU" connector has slightly shorter pins than the "HONDA' connector. Epson America, Inc. does not recommend the use of the EP-Connect interface that has the `FUJITSU' connector unless it is used on a unit that has the countermeasure described below. To identify which connector type the EP-Connect interface has, simply look directly at the interface connector. The "HONDA" connector will have the name "HONDA printed directly on the black part of the connector. If there is no label, it is the "FUJITSU" connector. Epson America, Inc. recommends the "HONDA" connector. There are approximately 1,600 of the EP-Connect interfaces on the market that contain the non-approved "FUJITSU" connector. To accommodate these interfaces Epson has taken a countermeasure on the DFX series printers. This involves adjusting the position of the ORII/F circuit board and changing the securing points. As a result, Epson only recommends the use of the Avatar board with the "FUJITSU" connector on DFX series printers that have the countermeasure installed. The starting serial number for the printers that have the countermeasure installed is outlined below.

EPSON Product Support Bulletin Subject: Quick Reference for 9/24 Pin Printer Paper Specifications Date: 10/9/92 Page(s): 1 of 1 PSB No: P-0022D Originator: SLS This PSB provides a quick reference for the paper specifications on Epson's current line of 9-pin and 24-pin dot-matrix printers when using continuous paper. The `Maximum No. of Copies" is the maximum allowable number of copies when using continuous multi-part carbonless paper. The "Total" number is the maximum allowable number of copies including the original. The `Maximum Total Thickness" is the maximum allowable total thickness including the original plus any copies. 9-PIN PRINTERS Model AP-2250 LX-810 FX-870/1170 DFX-5000 (Front Tractor) (Rear Tractor) DFX-8000 (Front Tractor) (Rear Tractor) l Orig. + Maximum No. of Copies 1 1 1 1 1 1 1 2 2 3 5 3 5 3 Total 3 3 4 6 4 6 4 Maximum Total Thickness I 0.0098" (0.25mm) I 0.0098" (0.25mm) I 0.0126" (0.32mm) 0.018' 0.012" 0.018' 0.012" (0.46mm) (0.30mm) (0.46mm) (0.30mm) 24-PIN PRINTERS Model AP-3250 * LQ-570/1070 LQ-860 LQ-870/1170 LQ-2550 * Note: I I Orig. + Maximum No. of Copies 1 1 1 1 1 1 3 3 3 5 I I I I I Total 2 4 4 4 6 Maximum Total Thickness 0.0071" (0.18mm) 0.0126" (0.32mm) 0.0126" (0.32mm) 0.0126" (0.32mm) 0.018' (0.46mm) I I I The AP-2250 and AP-3250 require an optional push tractor to use continuous paper. EPSON AMERICA, INC. EPSON Product Support Bulletin Subject: Quick Reference for Printer Acoustic Noise Levels PSB No: P-0016D Originator: SLS Date: 6/5/91 Page(s): 1 of 2 Sound intensity is measured in units called Bels (named after Alexander Graham Bell,) or more commonly in tenths of this fundamental unit: decibels. In making noise measurements a weighting network is applied in an attempt to match the frequency response of the instrument to that of the human ear. The most common is the A weighting network, with resulting measurements expressed in dB(A). The following is a list of current product's noise levels tested in accordance with standards set by the International Standards Organization (ISO). The acoustic noise levels for the 9 pin printers are averages while printing in Near Letter Quality (NLQ) mode using continuous paper and are not guaranteed figures. The acoustic noise levels for the 24 pin printers are averages while printing in Letter Quality (LQ) mode using continuous paper and are not guaranteed figures. The acoustic noise levels for the laser printers are averages while using single sheet paper and are not guaranteed figures. 9 PIN PRINTERS MODEL 1 NOISE LEVEL I I I IX-81 0 FX-850 FX-1050 DFX-5000 DFX-8000 I I 56 dB(A) 56 dB(A) 56 dB(A) 55 dB(A) 55 dB(A) II II II 24 PIN PRINTERS LQ-510 LQ-1010 11 LQ-850 1 56 56 dB(A) 56 dB(A) dB(A) 11 PSB No: P-0016D Page: 2 of 2 MODEL NOISE LEVEL LQ-860 LQ-1050 LQ-2550 55 dB(A) 55 dB(A) 55 dB(A) LASER PRINTERS
